Semi-Free Hamiltonian Circle Actions on 6-Dimensional Symplectic Manifolds
Assume (M,ω) is a connected, compact 6-dimensional symplectic manifold equipped with a semi-free Hamiltonian circle action, such that the fixed point set consists of isolated points or compact orientable surfaces. We restrict attention to the case dim $H^{2}(M)<3$ . We give a complete list of the...

| Zusammenfassung: | Assume (M,ω) is a connected, compact 6-dimensional symplectic manifold equipped with a semi-free Hamiltonian circle action, such that the fixed point set consists of isolated points or compact orientable surfaces. We restrict attention to the case dim $H^{2}(M)<3$ . We give a complete list of the possible manifolds, and determine their equivariant cohomology rings and equivariant Chern classes. Some of these manifolds are classified up to diffeomorphism. We also show the existence for a few cases. |
